Hello okay so I had my last regular period on the 9/02/11 and sex on the 15/02 and 18/02 my next period started on the 8/03 lasted 3days went away then came back but as light spotting for like an hour. I took a PT today and it had a faint as line come up at about 7mins after testing then got a little darker. I'm really confused and is it possible for a evaporation line to show up 7mins later? Also I have been feeling pregnancy symptoms, nausea (no vomiting) cramps, random cold (runny nose) headaches, back aches, notice my nipples are darker too.

Please help me!!
